Lab Testing for Bulk Solids
Bulkflow Technologies has fully equipped lab facilities to evaluate bulk solids. Product samples are tested with the following objectives:
- To evaluate the heat transfer properties and flow characteristics of the bulk solid;
- To determine the optimum plate spacing for the heat exchanger plates; and
- To assess the most effective type of discharge feeder.
Bulkflow determines the rate of heat dissipation for a layer of bulk solid material by using thermal conductivity testing. The measured value is used to determine the required heat transfer area for the Bulkflow Heat Exchanger.
The material sample is tested to determine particle size distribution, bulk density, moisture content and angle of repose. Mass Flow testing is performed in a clear test unit fitted with heat exchanger plates that are spaced at different intervals.
Test samples should be representative of the range of bulk solids to be handled by the equipment. Material Safety Data Sheets must be included with the sample, in accordance with government regulations.
Mass Flow Testing and Design
Solids Handling Technologies Inc. provides mass flow testing and consulting services to Bulkflow Technologies. Joe Marinelli is a bulk materials handling expert active in testing bulk solids and consulting on the design of bulk materials handling systems since 1972. Previously a consultant with Jenike & Johanson, he has years of practical experience testing bulk solids as well as designing feeders and hoppers for reliable flow.
Material flow property tests are done with a Jenike Shear Tester to determine wall slopes for mass flow and opening sizes to prevent bridging. The material flow properties determine the recommended feeder design.
On-Site Pilot Testing
Bulkflow Technologies has pilot testing equipment to demonstrate the operation of the Bulkflow Heat Exchanger at the customer`s plant under normal process conditions. The on-site pilot test is used to evaluate:
- thermal performance;
- product flow characteristics and heat exchanger plate spacing; and
- The operation of the discharge feeder.
The plate bank is comprised of three stainless steel heat exchanger plates with adjustable plate spacing. Material flow is observed through clear Plexiglas side panels. A variable speed discharge feeder regulates product flow through the unit. The pressure equipment collects heat transfer data during operation.
